The AS Series Accessory Shelf mounts below the optical table for out-of-the-way storage of bulky items like lasers and power supplies. Designed with robust, two-inch thick honeycomb paneling, covered by steel on all sides, the shelf is non-resonant. In fact, it’s guaranteed not to degrade table performance. If components require additional, positive-tie-down stability, Newport recommends using a breadboard and support posts instead. The AS-1568 requires holes to be drilled and tapped into the bottom surface of optical tables for attachment. Please notify your Newport representative so that this special feature can be added to the table.
